Quality Control: Learn More
The Intel QC8259A-2 is an NMOS interrupt controller designed for 8086, 8088, MCS-80, and MCS-85 bus compatibility. This component features 8 external interrupt inputs and operates with an 8-bit external data bus. Encased in a 28-terminal ceramic dual in-line package (CDIP), specifically R-CDIP-T28, it supports through-hole mounting with a terminal pitch of 2.54mm. The operating temperature range is specified from 0°C to 70°C, with a nominal supply voltage of 5.0V, ranging from 4.5V to 5.5V. Typical applications include industrial automation and embedded systems requiring robust interrupt management. The supply current maximum is 85mA.
